Abstract
Disclosed is a tomographic apparatus (100; 200; 300) wherein a camera (10) is provided with a converging collimator (120; 220; 320), and wherein a planar radiation beam makes a scanning movement to move an elongate illumination pattern (125; 225; 325) over the camera (10). In a first embodiment the collimator (120) is a fan beam collimator, and the radiation source (150) is a line-shaped radiation source which is rotatable about its longitudinal axis. In a second embodiment the collimator (220) is a fan beam collimator, and the radiation source (250) is a point-shaped radiation source which is movable along the convergence line (221) of the collimator (220). In a third embodiment the collimator (320) is a cone beam collimator, and the radiation source (350) is a point-shaped radiation source which is rotatable about an axis of rotation (357) which intersects the convergence point (321) of the collimator (320). As a result, a good image sharpness and a good separation of emission and transmission sources is accomplished.
